How to Use
Sort laundry and follow garment care labels. Fill the included scoop to line 1 for a medium load or line 2 for a large load, add the powder to the drum, then load clothes. In cold-water washes, let the machine fill for a moment so the powder dissolves before the clothes go in. To pre-treat a stain, mix a little powder with water into a paste, work it into the fabric, wait about five minutes, and wash as usual. For surfaces, dissolve a scoop in warm water and wipe with a cloth, then rinse. Store the box closed in a dry place, and keep it out of reach of children.

Frequently Asked Questions
Is Kirkland Signature Multipurpose Powder safe for HE washing machines?
Yes. The powder is formulated for both standard and high-efficiency washers, including front-load and top-load HE models. For HE machines, use the line 1 scoop measurement for a medium load to keep suds low. The formula is also labeled safe for septic tanks, so it suits homes on private systems as well as municipal sewer.
How much Kirkland powder detergent should I use per load?
Use the scoop that comes in the box. Fill it to line 1 for a medium load and to line 2 for a large or heavily soiled load. The 200-load count on the box is based on medium loads at line 1, so a household that mostly runs large loads should expect roughly half that number.
How should I store Kirkland laundry powder and is it safe around children?
Keep the box closed and dry, away from moisture that would cause the powder to clump. Store it out of reach of children and pets, as with any laundry detergent. If powder gets in the eyes, rinse with water for fifteen minutes, and contact a poison control center or doctor if any is swallowed.
Where is Kirkland Signature Multipurpose Powder made?
It is made in the USA from US and imported parts and distributed by Costco Wholesale Corporation. Real Prime Deals sells it as a single 348.8 oz (21.8 lb, 9.88 kg) box rated for 200 medium loads, the same box sold in Costco warehouses, so you get the full-size format without a membership.
